嘿嘿。咱中国的蛋白质造假终于把老美给玩急了！
蛋白质造假，是一个天才般的化学应用，把那些氮含量高、但毫无营养价值的便宜物质，掺到饲料或者宠物食物当中去，化验结果很好，但实际上并没有那么多可吸收的蛋白质。我怀疑这种缺德的科学知识不是咱中国科学家的发明，倒有可能是港台东南亚华裔商人在大陆开办饲料企业，商业机密外泄的结果。（好像中央电视台前几年的《正大综艺》节目就是泰国养猪饲料公司出钱搞来打知名度的。）
这是今天《纽约时报》发自山东章丘的报道，指饲料中掺假，在中国是公开的秘密。所掺的假，居然是从煤提取出来的工业废料。
卖给农民兄弟们的养猪饲料，不知被蒙蔽了多久了。
现在，美国的狗让中国饲料原料给毒死了，这下美国佬急了。
可中国仍然不许报道这事。尤其不许报道把美国狗死和中国出口饲料联系起来。
Filler in Animal Feed Is Open Secret in China Ariana Lindquist for The New York Times

ZHANGQIU, China, April 28 — As Americanfood safety regulators head to China to investigate how a chemical madefrom coal found its way into pet food that killed dogs and cats in theUnited States, workers in this heavily polluted northern city openlyadmit that the substance is routinely added to animal feed as a fakeprotein.

The Shandong Mingshui Great Chemical Company makes a chemical calledmelamine and sometimes sells melamine scrap to other producers who useit to make animal feed.
For years, producers ofanimal feed all over China have secretly supplemented their feed withthe substance, called melamine, a cheap additive that looks likeprotein in tests, even though it does not provide any nutritionalbenefits, according to melamine scrap traders and agricultural workershere.
“Many companies buy melamine scrap to make animal feed,such as fish feed,” said Ji Denghui, general manager of the FujianSanming Dinghui Chemical Company, which sells melamine. “I don’t knowif there’s a regulation on it. Probably not. No law or regulation says‘don’t do it,’ so everyone’s doing it. The laws in China are like that,aren’t they? If there’s no accident, there won’t be any regulation.”
Melamineis at the center of a recall of 60 million packages of pet food, afterthe chemical was found in wheat gluten linked this month to the deathsof at least 16 pets in the United States.
No one knows exactlyhow melamine (which is not believed to be particularly toxic) became sofatal in pet food, but its presence in any form of American food isillegal.
The link to China has set off concerns among critics of the Food and Drug Administrationthat ingredients in pet food as well as human food, which areincreasingly coming from abroad, are not being adequately screened.
“Theyhave fewer people inspecting product at the ports than ever before,”says Caroline Smith DeWaal, the director of food safety for the Center for Science in the Public Interestin Washington. “Until China gets programs in place to verify the safetyof their products, they need to be inspected by U.S. inspectors. Thisopen-door policy on food ingredients is an open invitation for anattack on the food supply, either intentional or unintentional.”
Now,with evidence mounting that the tainted wheat gluten came from China,American regulators have been granted permission to visit the region toconduct inspections of food treatment facilities.
The Food andDrug Administration has already banned imports of wheat gluten fromChina after it received more than 14,000 reports of pets believed tohave been sickened by packaged food. And last week, the agency opened acriminal investigation in the case and searched the offices of at leastone pet food supplier.
The Department of Agriculture has alsostepped in. On Thursday, the agency ordered more than 6,000 hogs to bequarantined or slaughtered after some of the pet food ingredients lacedwith melamine were accidentally sent to hog farms in eight states,including California.
Scientists are now trying to determine whether melamine could be harmful to humans.
Thepet food case is also putting China’s agricultural exports undergreater scrutiny because the country has had a terrible food safetyrecord.
In recent years, for instance, China’s food safetyscandals have involved everything from fake baby milk formulas and soysauce made from human hair to instances where cuttlefish were soaked incalligraphy ink to improve their color and eels were fed contraceptivepills to make them grow long and slim.
For its part, Chineseofficials dispute any suggestion that melamine from the country couldhave killed pets. But regulators here on Friday banned the use ofmelamine in vegetable proteins made for export or for use in domesticfood supplies.
Yet what is clear from visiting this region ofnortheast China is that for years melamine has been quietly mixed intoChinese animal feed and then sold to unsuspecting farmers asprotein-rich pig, poultry and fish feed.
Many animal feedoperators here advertise on the Internet, seeking to purchase melaminescrap. The Xuzhou Anying Biologic Technology Development Company, oneof the companies that American regulators named as having shippedmelamine-tainted wheat gluten to the United States, had posted such anotice on the Internet last March.
Here at the Shandong MingshuiGreat Chemical Group factory, huge boiler vats are turning coal intomelamine, which is then used to create plastics and fertilizer.
But the leftover melamine scrap, golf ball-size chunks of white rock,is sometimes being sold to local agricultural entrepreneurs, who saythey mix a powdered form of the scrap into animal feed to deceive thosewho raise animals into thinking they are buying feed that is high inprotein.
“It just saves money if you add melamine scrap,” said the manager of an animal feed factory here.
LastFriday here in Zhangqiu, a fast-growing industrial city southeast ofBeijing, two animal feed producers explained in great detail how theypurchase low-grade wheat, corn, soybean or other proteins and then mixin small portions of nitrogen-rich melamine scrap, whose chemicalproperties help the feed register an inflated protein level.
Melamine is the new scam of choice, they say, because urea — anothernitrogen-rich chemical — is illegal for use in pig and poultry feed andcan be easily detected in China as well as in the United States.
“People use melamine scrap to boost nitrogen levels for the tests,”said the manager of the animal feed factory. “If you add it in smallquantities, it won’t hurt the animals.”
The manager, who worksat a small animal feed operation here that consists of a handful ofstorage and mixing areas, said he has mixed melamine scrap into animalfeed for years.
He said he was not currently using melamine.But he then pulled out a plastic bag containing what he said wasmelamine powder and said he could dye it any color to match the rightfeed stock.
He said that melamine used in pet food would probablynot be harmful. “Pets are not like pigs or chickens,” he said casually,explaining that they can afford to eat less protein. “They don’t needto grow fast.”
The resulting melamine-tainted feed would be weak in protein, he acknowledged, which means the feed is less nutritious.
But, by using the melamine additive, the feed seller makes a heftierprofit because melamine scrap is much cheaper than soy, wheat or cornprotein.
“It’s true you can make a lot more profit by puttingmelamine in,” said another animal feed seller here in Zhangqiu.“Melamine will cost you about $1.20 for each protein count per tonwhereas real protein costs you about $6, so you can see the difference.”
Feed producers who use melamine here say the tainted feed is oftenshipped to feed mills in the Yangtze River Delta, near Shanghai, ordown to Guangdong Province, near Hong Kong. They also said they knewthat some melamine-laced feed had been exported to other parts of Asia,including South Korea, North Korea, Indonesia and Thailand.
Evidence is mounting that Chinese protein exports have been taintedwith melamine and that its use in agricultural regions like this one iswidespread. But the government has issued no recall of any food or feedproduct here in China.
Indeed, few people outside theagriculture business know about the use of melamine scrap. The Chinesenews media — which is strictly censored — has not reported much aboutthe country’s ties to the pet food recallin the United States. And few in agriculture here do not see any harmin using melamine in small doses; they simply see it as cheating alittle on protein, not harming animals or pets.
As for the sale of melamine scrap, it is increasingly popular as a fake ingredient in feed, traders and workers here say.
Atthe Hebei Haixing Insect Net Factory in nearby Hebei Province, whichmakes animal feed, a manager named Guo Qingyin said: “In the pastmelamine scrap was free, but the price has been going up in the pastfew years. Consumption of melamine scrap is probably bigger than thatof urea in the animal feed industry now.”
And so melamine producers like the ones here in Zhangqiu are busy.
Aman named Jing, who works in the sales department at the ShandongMingshui Great Chemical Group factory here, said on Friday that priceshave been rising, but he said that he had no idea how the company’smelamine scrap is used.
“We have an auction for melamine scrapevery three months,” he said. “I haven’t heard of it being added toanimal feed. It’s not for animal feed.”
